awful.ewmh: doc improvements / TODOs

[blueyed]

I've used a custom ewmh.activate function myself, and converted this to a filter now.

Firefox focus stealing appears to have been fixed (or I could not trigger it yet again), so the only thing I like is activating the (first) tag of a client if it's not visible with "ewmh" request (e.g. when opening a web page via xdg-open or using Slack's notification bar icon; by default non-visible clients get marked as urgent only.
